Update::: I am back on the tiger cat, here is what happened, first the first part of the folding wing part were not up to snuff, I made some mistakes and decided to start over, so far going well, but the other reason it was on hold, is my investing partner also wants to do the Boeing XF8B from 1944 , so we started to calculate which engines would ready first, the R18 or the R28, so with the R18 are the front runners , then we go forward with the F7F and this is when I say , "Are we having fun yet"
